A geostationary satellite follows a circular orbit inside plane of the Equator at a height of 35,600km, making sure that it appears to hover more than a selected stage on the Earth's surface. 3 such satellites are sufficient to cover most in the globe, and mobile users hardly ever must switch from one satellite to an additional. Other mobile satellite methods use larger numbers of satellites in lower, non-geostationary orbits. On the user's stage of view, they move across the sky at a comparatively high speed, usually requiring a switch from one satellite to a different in mid-communication and definitely risking the chance of an interrupted call.

The Inmarsat-3 satellites are backed up by a fifth Inmarsat-3 and four previous-generation Inmarsat-2s, also in geostationary orbit.
A critical benefit of the Inmarsat-3s over their predecessors is their potential to generate a quantity of spot-beams in addition as single big world wide beams. Spot-beams concentrate additional power in areas of substantial demand as well as making it doable to supply regular products and services to smaller, simpler terminals.
